Informatica: Source multiple files Dynamically

Informatica allows to source multiple files which have same structure and similar information.
Lets say we have month wise sales information in files.

1. Jan2017_Sales.txt
2. Feb2017_Sales.txt
3. Mar2017_Sales.txt

and we need to load all of them in sales table in 1 go.

To do so, we will build our mapping and workflow exactly in same way as we build for single file. Only change will be in workflow property.

Select the source object and set following properties.

Source filetype = Indirect

Source filename = *_Sales.txt

As shown in figure below.
